The WAI-Core Project, funded by NIDILRR at the US HHS,
provides support for accessibility work at W3C WAI to:

Task 1:

Provide staff support and technical expertise within a Working Group
of Web accessibility experts representing different stakeholder
groups, including via recruitment of public comments on draft
technical reports from other W3C Working Groups, W3C Interest Groups
and W3C Community Groups, and as needed to develop technical
specifications that support accessibility, such as WAI-ARIA and
Accessibility Application Programming Interface (API) mappings;

Update documentation as needed of accessibility experts’ guidance on
accessibility requirements, specification design considerations, and
known gaps, drawing on experience gained from reviewing resolutions to
accessibility barriers in a wide range of Web technologies, to serve
as a general introduction to accessibility self-review by other W3C
working groups and to facilitate the scaling of accessibility
expertise to a larger number of W3C specification reviews (currently
Web Technology Accessibility Guidelines (WTAG)).

Task 2:

Maintain one or more multi-stakeholder Working Groups of Web
accessibility experts to develop updated guidance and technical
support materials on Web content and applications, authoring tools,
browsers, mobile applications, and other Web-enabled applications,
devices and services; This may be in stand-alone, combined or modular
format, including extensions of previous guidelines, or as updated
combinations of previous guidelines. It may include accessibility
guidance and technical support materials for technologies relating to
industries newly converging with the Web, for example mobile, digital
publishing, Web of things, TV and Web, education, health care, or
other areas; and may include extensive guidance and/or techniques for
areas such as cognitive and learning disability, low-vision
accessibility, and/or voice input accessibility.

Task 3:

Review, provide analysis of, and comment on understandability,
readability of and usability of accessibility standards and
implementation reference materials; develop non-technical
introductions to accessibility guidelines and standards, and overviews
of accessibility user requirements for people with disabilities;
provide education and outreach activities to support acceptance of Web
accessibility guidance; comment on draft standards, regulations,
and/or policies where necessary to promote acceptance of Web
accessibility solutions.

Education and Outreach Working
Group (EOWG) (participation
in EOWG) for improving understanding and usability of
accessibility standards and implementation reference materials,
developing non-technical introductions to accessibility guidelines and
standards, and providing education and outreach to support
implementation of Web accessibility guidance.

In addition to participation opportunities, everyone is welcome to
review drafts. Draft in progress are highlighted on the WAI
home page. To get notifications of drafts for review, see Getting WAI
Announcements for links to WAI tweets, RSS feed, and WAI Interest
Group (WAI IG) emails.
